Seems like a second iteration of this issue...
I navigate to https://stackoverflow.com/questions/tagged/javascript and alas, the questions don't even have a javascript tag:
I opened the link in Incognito (Chrome 114) and it shows the same thing. The expected behavior would be that the questions are all tagged with the correct tag.
[Edit]
Seems like the issue just corrected itself, but apparently the bug's still existent.
